fixing problem in which scope.survey.questions was not the complete
list of questions. experimented with hard-coding the centroid of each
grid cell into the geojson but this does not fix the problem in which
the label generation slows everything down in the map multipolygon
question.  enabled map-multipolygon in mobile app - had to address some
css issues. also provided a more useful output for the page list in the
admin.
updating usvi survey with new 2.5 minute fishing grid (still not covering Puerto Rico)
tweaking the map tiles for the labels.  map question is close to complete now.  also updating the survey so the pages are all assigned appropriate blocks (skip conditions).
